摘要
移民搬迁使贫困人口实现了生计空间的再造和家庭资产的重塑。文中借助2017年六盘山片区548户农户家庭微观调研数据,采用倾向得分匹配法,研究了移民户与非移民户的家庭资产变化情况。研究表明:在其他因素保持不变的情况下,生态移民工程的实施使得农户总资产得到显著的提高,同时改变了农户的资产持有结构。其中移民对农户的自然资源与生产性固定资产持有量具有负向影响;对农户金融资产影响不明显;对农户非金融资产中的房产持有量有正向的影响。另外,我们还发现,运用传统的回归方法来评估移民效应会明显低估移民政策真正的正面作用,同时放大其负面影响。
Poor people could change household assets by migration.By means of the micro survey data of 548 households at Liupanshan district in 2017,propensity score matching was adopted to analyze the transformation of household assets for immigrant and non-immigrant households.Research shows that the implementation of the ecological migration project has significantly improved the total assets and changed their structures.In addition,we also found that using traditional regression methods to assess the migration effect significantly underestimated the positive effect of immigration policy,while magnifying its negative impact.Based on the above conclusions,we put forward relevant policy recommendations.
